296 MR. A. O. WALKER ON THE 
Telson elongate triangular, about as long as the uropods, with 
6 or 7 short spines on each margin, and a few divergent set on 
the apex which is rounded. ; 
Length 3 mm. 
The genus Hyssura has hitherto been known only from a 
single specimen of H. producta described by Norman & Stebbing 
in their “ Isopoda of the ‘ Lightning,’ &c.” (Trans. Zool. Soc. 
vol. xii. Part iv. 1886, p. 128, pl. xxv. fig. v.), and dredged by 
H.M.S. ‘ Valorous’ in 1875 in the North Atlantic in lat. 56° N., 
long. 37 W., in 1450 fath. It is difficult to imagine a greater 
contrast in the conditions of life than exists between the bright 
light and high temperature of the Mediterranean, where I could 
plainly see the bottom with its alternate patches of weed and 
sand, and the cold and darkness of the Atlantic at such a depth! 
Yet the apparent differences of structure are very slight—only 
the relative proportions of the first 3 pairs of legs, and the spines 
on the uropods and telson, which do not exist in the Atlantic 
species. There is no vestige of eyes in either species.
